Forged Steel Gate Valves are meticulously designed and manufactured in strict compliance with international standards such as API 602, ASME B16.34, DIN 3202, or their equivalents. These valves feature a compact yet extremely robust design, making them suitable for high-pressure and high-temperature applications. An optional solid CoCr alloy wedge ensures low friction and extended service life. The packing rings are precompressed to 4000 psi, providing a highly reliable seal. For welded bonnet valves, the bonnet is threaded in and torqued to a specified engineered torque value, and the body-bonnet joint is strength-welded, offering dual protection against leakage through the combination of body and bonnet threads and the strength weld. The fully guided wedge minimizes wear on seating surfaces. Additionally, an optional design is available with features such as double packing, a leak-off connection, live-loading, and a packing blowout for easy removal of old packing.
